Interleukin-6 Receptor Inhibition for Symptomatic Intracranial Atherosclerosis — IRIS-sICAS  

Stroke Clinical Trial

Official title:
Effect of Interleukin-6 Receptor Inhibition for Avoiding Recurrence of Ischemic Stroke in Patients With Symptomatic Intracranial Atherosclerosis: a Double-blind, Randomized, Placebo-controlled Trial

Clinical Trial Summary

IRIS-sICAS is a multicenter, randomized, double-blind, placebo-controlled clinical trialis a multicenter, randomized, double-blind, placebo-controlled clinical trial, to assess the safety and efficacy of tocilizumab injection in lowering the incidence of newly diagnosis ischemic stroke and improving prognosis in symptomatic intracranial atherosclerosis patients.

Clinical Trial Description

Intracranial atherosclerosis (ICAS) is one of the most common causes of stroke worldwide, and the currently recommended intensive pharmacologic and surgical treatments show only modest efficacy, with approximately 20% of strokes still recurring, for which there is no targeted treatment. Tocilizumab is a recombinant humanized anti-human interleukin-6 receptor monoclonal antibody that exerts anti-inflammatory effects by specifically binding to the IL-6 receptor and blocking IL-6 signal transduction. Previous studies have shown that tocilizumab can effectively attenuate acute ischemic injury in the early stage of myocardial infarction and has potentially anti-atherosclerotic effects. However, application in ICAS not yet reported. This study is a multicenter, randomized, double-blind, placebo-controlled clinical trial, which enrolled patients with symptomatic ICAS occurring within 72 hours of ischemic stroke or high-risk transient ischemic attack. Patients who consented to participate in the study were randomly assigned in a 1:1 ratio to receive a single infusion of 320mg tocilizumab or placebo (saline injection), and patients were followed up to assess the safety and efficacy of tocilizumab injection in lowering the incidence of newly diagnosis ischemic stroke and improving prognosis. ;
